- updated to SignalR 2.0.3 as well as other updated dependency versions listed below. This required eliminating the Configuration class with its pre-startup execution and moving its initialization code into an IAppBuilder extension method that can be called within an Owin Startup class. This also allows changing the previously-forced default configuration assumptions (e.g. EnableDetailedErrors = true). See AppBuilderExtensions and the demo's Startup class for coding details.

- also updated to .NET 4.5, Microsoft.Owin 2.1.0, Rx 2.1.30214.0, jQuery 2.1.0, Newtonsoft.Json 6.0.3, Entity Framework 6.1.0, Modernizr 2.7.2.
- enabled nuget package restore on the solution while eliminating the nuget packages folder so avoid bloating the repo with binaries.
- updated .gitignore to ignore nuget packages, debug and release folders, and jmconfig files.
